2-minute Review [Positives]
  • Stunning looks, similar rainbow-like effects at the back as the Galaxy A50s when caught against the light, and a prism-like pattern that Samsung calls a “3D prism design” - it's a head-turner no doubt
  • While it supports a polycarbonate back, it still manages to look premium
  • The front looks stylish and modern too with a single punch-hole in the upper middle of the display
  • Compact and light for the display size and battery capacity, at just 172g, and 7.9mm in thickness
  • Bright, large 6.5-inches Super AMOLED panel with a full-HD+ resolution - its punchy colours make it a joy to stream content, while games also look great on the panel because of its high colour accuracy
  • There's Widevine L1 support by default, which makes streaming content in HD possible
  • Comes with Android 10 out of the box - Samsung's One UI 2 is now one of the better, more clean and streamlined Android UIs around, and is well optimised for modern large displays (like this one)
  • Samsung has also added some neat features including a Game Booster and an intuitive gesture-based navigation system
  • Decent performance with the same Exynos 9611 processor as the Galaxy A50s (similar to Qualcomm Snapdragon 660/665) - the experience is fairly smooth throughout with games like PUBG Mobile and Asphalt 9
  • Decent quad camera setup at the back - a 48MP primary sensor + 12MP wide-angle camera + 5MP macro camera + 5MP depth sensor
  • Under good light, the Galaxy A51's primary camera managed to capture detailed shots with good dynamic range - images are reasonably sharp, noise is also competently removed, colours are generally nice, and the phone strikes a good balance with saturation
  • The ultra wide-angle cam is a significant upgrade from the one on the A50s, and it offers improved sharpness and detail - dynamic range is also substantially better, making for an altogether pretty capable ultra-wide camera as far as mid-rangers go
  • Macro camera turns out quite good close ups - you can get a lot closer to your subject when using the macro camera and the sensor picks up a fair bit of detail
  • Very good portrait mode ("Live focus") - image quality is good and the depth camera helps the Galaxy A51 do a decent job of edge detection
  • The front 32MP camera is decent and produces nice colours, the detail is quite good as far as selfie cameras go - portrait selfie mode is decent too
  • Decent video recording from both primary and wide cameras with dedicated 'super steady' mode which allows you to shoot decent “action” videos (though stabilisation is not available at 4K)
  • Decent bottom-firing speaker - sufficient for personal listening
  • Solid, dependent battery life from the 4000 mah battery - will easily manage to get a day and a half's worth of regular use
  • Reasonable 15W fast charging - charges 67 percent in an hour (though, not as quick as others in this segment such as the Redmi K20 Pro)
  • Overall, a decent and likeable smartphone from Samsung - offers a polished experience, a slim and light body, solid battery life, a crisp display, and of course the Samsung brand (though, the performance at this price is a letdown)
  • Gorgeous design, with a stunning prism light effect
  • The back is well rounded around the sides to make handling easier, and blends in with the curved glass on the front seamlessly
  • Has a good grip
  • The handling is also made easy by the excellent weight distribution of the phone which makes it seem a lot lighter than it is
  • Absolutely gorgeous, 6.7-inch Super AMOLED display, with a tiny water drop notch and a near bezel-less design - you get very vibrant colours and perfect inky blacks, as well as good sunlight legibility
  • Video viewing and gaming experience on the giant display is an absolute delight - as far as media consumption goes, this is simply one of the best phones out there, period
  • Running the Galaxy A70 is Samsung's new OneUI - which, as far as Android UIs go, is one of the most refined, well thought-out experiences
  • There are many useful add-ons on board - like gesture navigation, and a great 'dark' mode
  • Samsung Pay makes the cut too, making this the cheapest phone to sport the full version of the payments app, which will be especially useful if your usage usually relies largely on card payments
  • Good performance backed by the robust Snapdragon 675 SoC, 6 GB of RAM, and super fast UFS storage - everything from daily use to complex games like PUBG is fairly smooth (add that to the ridiculously wide display, and all gamers are in for a treat)
  • Decent triple-camera setup on the back with a primary 64-megapixel f/1.7 sensor, a secondary ultrawide 8-megapixel shooter and a third 5-megapixel depth sensor - images come out nice with true to life colors
  • The ultra-wide sensor provides some extra shot framing options
  • Decent video recording performance with good detail levels, including some impressive slow-mo video recording
  • Very good front camera - the 32-megapixel sensor does a great job at bringing out the detail in facial features and hair
  • The bundled in-ear earphones, when paired with Dolby Atmos, makes for a pretty good audio experience
  • The loudspeaker is decent (though not exceptional)
  • Very good battery life with a large 4500 mAh battery - it will comfortably last you a day and more, even with that large display
  • There is also fast charging on-board, with the included 25W charger getting you up to around 70% in an hour
  • If you are looking for the best media consumption device for your money, the Galaxy A70s is a good option - the large, beautiful Super AMOLED display + the big battery + Dolby Atmos support - make for an excellent combo
2-minute Review [Negatives]
  • The in-display fingerprint sensor as well as the facial recognition are on the slower side
  • The glossy body is prone to picking up fingerprints
  • There's still some bloatware pre-installed, including third-party apps and some of Samsung's own apps such as Samsung Shop (though most of them can be uninstalled)
  • At this price, the performance feels weak - there are cheaper phones that offer much better performance, like the Redmi K20 & the Realme X2
  • Low light photos out of the Galaxy A51 aren't great (from all cameras) - The output is soft and noisy, while the colours are relatively desaturated
  • Overall, while the Galaxy A51 offers good cameras, there are certainly better options available, such as the Redmi K20 Pro
  • However, as far the value for money goes, the Galaxy A51 is far behind from the competition - there are better options like the Redmi K20 Pro which gets you a flagship-grade processor, an HDR display, more premium materials, and even better cameras - in fact, for a bit less money, you could also get the Redmi K20, which is also very capable
  • This is a large phone though (one of the largest mainstream phones currently available), so one-handed use is pretty much out of the question - people with small hands would also want to look at other options
  • The glossy back is of course a smudge magnet, and will also pick up scratches easily
  • Having said that, there are certainly even better performing competitors around
  • Details and dynamic range on the rear camera setup could also be a bit better
  • Overall, for the price bracket, the camera package on the Galaxy A70 is decent, but not the best - you will find better camera phones in the competition
  • On the other hand, the competition is pretty tough - in the Xiaomi and Realme phones in this price bracket, you will find better performance, arguably better cameras, and more manageable sizes
